Which JMP function can generate a non-repeating integer between two values?

Question

I tried “Random Integer()”, but it produces duplicate integers. Thanks!

I do not believe there is such a function in JMP, but it is very simple to create one

Names Default To Here( 1 );

uniqueRandomInteger = Function( {n, min, max},
	{defaultlocal},
	hold = [];
	For( i = 1, i <= n, i++,
		val = Random Integer( min, max );
		While( N Rows( Loc( hold, val ) ) > 0,
			val = Random Integer( min, max )
		);
		hold = hold |/ Matrix( val );
	);
	hold;
);

x=uniqueRandomInteger(10,100,200)

@lwx228 ,

This is just an alternate method relying on the JMP function Random Shuffle

Names Default to Here(1);

ibeg = 257;

iend = 500;

random_all = As List( Random Shuffle( Transpose(ibeg::iend) ) );

//suppose you only want 100

vals = random_all[1::100];

show(random_all, nitems(random_all), iend-ibeg+1 );

show(vals, nitems(vals));

I felt like a slacker, given Jim's elegant function. [grin] The attached script includes a function that uses this range/shuffle/subset  method.  Jim, @txnelson,  your function name was spot on, so I used it.
